| 摘 要： | 频率选择表面是二维周期性阵列结构,通常由导体贴片和介质或由周期性开孔的导体屏和介质构成,与入射电磁波相互作用时表现出明显的带通或带阻的滤波特性.采用模匹配技术对带通型频率选择表现进行分析,其中单元内的场用有限元法解出.这种方法对任意单元形状的频率选择表面都适用.

| Abstract: | Frequency selective surface is formed by two-dimension periodic array structure,which is always constructed by the conductive paste and dielectric of the periodic aperture conductive screen and dielectric.The filtering character of bandpass and bandstop is obviously shown when electric-magnetic wave react with the surface.Bandpass FSS is analyzed by mode matching technology.With this technology,the field in the elements can be solved by finite element method.This method can be applied in analyzing arbitrary element,which is the good character of the method. |
